Julien, Jan, Andrew,
The problem addressed by [1] causes random ARM64 boot fails dependent on
hypervisor code changes.
Yet more generic solution was requested by Andrew and supported by Julien [2].
How to proceed with this particular patch?
As I understand, Jan doubts we should move page alignm

You probably want to describe where this goes wrong currently on ARM here.

Let vunmap align passed virtual address by PAGE_SIZE.
This also makes it consistent with how {,un}map_domain_page()
currently works.
With the main change, also:
- strip all existing vunmap() calls from prior masking
- replace opencoded PAGE_MASK macro in vm_index()
